does not return until the Java side sends an expression of the form EvaluatePacket[EndModal[args]].


  • To use DoModal, you first need to load J/Link using Needs["JLink`"].
  • DoModal returns EndModal[args].
  • Use DoModal to have a program wait until some Java user-interface action signals that it can proceed.
  • Typically, this would be used to implement a modal dialog box that needs to return a result to the Wolfram Language when it is dismissed.
